It has also ensured that no form of censorship of information is practised since data storage does not have one dictator. It is self-evident that this will lead to the next phase of the internet revolution.

Additionally, it offers a trustless, distributed network where no single entity can control the flow of information. This decentralization mitigates the risks of censorship and failures associated with centralized systems, guaranteeing secure, transparent transactions.

Decentralized networks also present exciting opportunities for social media platforms. Unlike traditional centralized platforms, decentralized social media platforms empower users by ensuring freedom of expression, data ownership, and resistance to censorship. Transactions and interactions occur on blockchain-based protocols, preserving privacy and security while enhancing engagement.

Key Features of Blockchain in Web3:

• Decentralization: Information is distributed across a network of nodes, eliminating a single point of control. This ensures that no one entity has dominance over the system, making censorship impossible. Each node in the network of nodes plays a crucial role in maintaining decentralization, verifying transactions, and ensuring the integrity of the system.
• Immutability: Once data is added to the blockchain, it cannot be altered or erased, ensuring data integrity and fostering trust in digital interactions.
• Smart Contracts: These self-executing contracts automate processes by executing code when specific conditions are met. This eliminates intermediaries, reduces costs, and enables decentralized applications (dApps), ranging from decentralized finance (DeFi) platforms to NFT marketplaces. 
• Tokenization: Blockchain enables the creation of digital assets like cryptocurrencies, NFTs, and tokenized physical assets. These tokens fuel the Web3 economy by enabling secure, peer-to-peer transactions and crowdfunding opportunities.

 Example
